Security Devices |
 |
|
I’ve been thinking about buying a security system for a while now, but I don’t know that much about them. How do they work? |
|
 |
A security system starts with a control panel. Usually located in a
closet or a basement, the control panel contains the "brains" of the
security system, and essentially operates as a central computer.
Various sensors connect to the control panel from locations throughout
your home. If your security system is armed and the sensors detect a
problem, they send signals to the control panel. The control panel
automatically dials the central monitoring station, where the proper
authorities are notified. |
|
What does the keypad do? |
|
 |
You operate your security system by entering your
security code at the keypad. Generally located at entry doors,
keypads can arm and disarm with push-button ease, and literally put
security at your family’s fingertips! Good features to look for
include illuminated keys to provide you with greater visibility at
nighttime, easy-to-read English displays that spell out your
system’s status at a glance, and one-touch function keys that
provide single-button operation for arming, disarming or
emergencies. Most keypads even offer convenient additional user
codes to give friends, neighbors or service people access to your
home. |
|
What are magnetic contacts? |
|
 |
Magnetic contacts are two-part devices used to
safeguard windows and doors. One part of the contact is a switch
installed in the window or door jam; the other contains a magnet and
is placed in the window or door itself. Any noticeable shift in
contact with the switch results in an alarm. |
|
What is a PIR? |
|
 |
A passive infrared motion detector (PIR) is an
electronic security device that detects intruders by "sensing"
motion or body heat in the area being protected. Most PIRs are
designed to be used when your family is away from home or when no
one will be passing through the area "covered" by the PIR. |
|
I have a dog! Does that mean I can't install a PIR? |
|
 |
Absolutely not. Recent innovations in security
technology have resulted in the creation of "pet immune" motion
detectors-allowing dog and cat lovers to enjoy the same level of
protection they would receive with a standard PIR. These
state-of-the-art sensors provide "pet immunity" for animals weighing
up to 100 lbs. Pet immune PIRs allow your pet to move about freely
but can still detect an intruder’s movement. |
|
Speaking of sensors, how are the "glassbreak" kind
operated? |
|
 |
"Acoustic" glassbreak sensors, usually mounted on
ceilings or walls, work by "listening" for the sound of breaking
glass in a window. "Shock" glassbreak detectors are mounted on the
window and "feel" the shock of breaking glass. This kind of advanced
wireless technology can provide shatter and shock protection for
your windows, for often intruders are "sensed" and an alarm sounded
while they are still outdoors. This is often enough to send a
burglar running! |
|
I already have a battery-operated smoke detector, so
why would I need one installed as part of my security system? What’s
the difference? |
|
 |
Since you own a smoke detector, you obviously
realize what an important safety measure this device is. That’s
good. Smoke detectors are highly effective in preventing loss of
life and property. However, there are differences between the "stand
alone" or battery-operated smoke detector you would buy at your
local hardware store and one installed as part of your home security
system.
"Stand alone" detectors are not connected to other detectors or
warning devices. A smoke detector connected to your security system
offers more protection because it is monitored by a central station.
If fire strikes, the detector sets off an alarm and sends a signal
to the control panel. The control panel dials the central station,
where the operator notifies the fire department. Only central
station monitored smoke detectors provide automatic notification of
authorities when you or your family are asleep, not at home or
unable to get to the phone. |
|
I’ve been hearing so much about these "wireless"
security devices. Do they really work well, and are they easy to use? |
|
 |
Yes on both counts! Technological breakthroughs
have led to the development of wireless electronic security
products, and their effectiveness has been proven time and again
over the years in millions of installations. Their rock-solid
stability and long battery life make them a popular choice among
homeowners and dealers alike. They give installers the flexibility
they need to overcome obstacles like brick walls, cement floors and
cathedral ceilings; and no drilling holes preserves the beauty of
your home and results in cleaner, faster installations.
Folks today enjoy the convenience of remote control devices, and the
security industry has responded! User-friendly wireless products
provide the dual benefits of superior performance and ease of
operation. Wireless keypads allow you to activate and de-activate
your security system with the touch of a button, and can even be
programmed so that a young child can operate it with ease.
Homeowners especially love wireless keys! Similar in size to a
remote car alarm key, they fit right on your keychain, and the press
of a single button lets you control your system, lights and
appliances-eliminating the need for codes. This is especially great
if you and your family enjoy spending time outdoors. Relax by the
pool, garden, barbecue and entertain, or play with your kids in the
backyard-enjoy extra mobility without compromising your safety!
Another hot item gaining popularity is the interactive phone module.
By adding the phone module to your home security system, you’ll have
remote control access from any touch-tone or cellular phone-from
your office, on the road, or anywhere in the world! Conveniently
arm, disarm or check the status of your system, turn your lights on
or off-you can even control your thermostat and air conditioner! | |
